perf: evsel: Fix error handling in tp_format lookup

Browse source

In evsel__tp_format(), when trace_event__tp_format*() returns an error,
IS_ERR() checks the local variable 'tp_format', but PTR_ERR() incorrectly
uses 'evsel->tp_format' which hasn't been assigned yet.

Fix this by using PTR_ERR(tp_format) to extract the error code from the
correct variable.
